1. There are cheaper PSUs out there that are still quality. Look into OCZ StealthXStream or GameXStream, both of which can be as low as $60 (for 700W).

2. For you HSF get the Cooler Master Hyper 212+. It is the best bang for your buck and in the same price range as that Arctic Cooling one. (See this article)

3. ATI is destroying nVidia with they're new 5xxx video cards. Go for the 5850 (~$300) or if you're willing to go up a little more the 5870 (~$400)

4. If you're just gaming (with a little video encoding, depending on your definition of little) you won't need more than 4GB of RAM. 4GB is a great number to suggest because you will be able to do anything you want with that, but if you find that it's a little slow, you could always go back and grab another 4GB. I just don't want you spending $140 when it might not even help you significantly.

I haven't looked into the parts people recommended to me yet, but one thing I should mention is that I selected 2 sets of the 4 gig kits. It is easy to miss, I apologize that I didn't mention it in the first post

@ madadmiral, why do you recommend that cooler master cast over the antec 902?

Ya, I realized you picked 2 sets of 4GB kits, but 8GB isn't really necessary by today's standards, which is why I suggested starting with one kit and then if you felt like it was necessary getting another kit. The HAF 922 was suggested because it's $40 cheaper, bigger (even though it's still called a mid tower it's bigger than some full towers) and has amazing airflow for cooling. You can also add a few other fans to make it an air cooling beast. I should've mentioned the HAF 922 switch but it completely slipped my mind.

Memory - Don't see a value to DDR3-2000.....DDR3-1600 gets you to 4 Ghz and more, so really don't see the need to g0 higher unless you thinking LN2 cooling. Plus it's CAS 9 ! Long way from CAS 6 or 7. Here's CAS 6 for $10 more

GFX - I'm assuming you selected this card specifically to play PhysX games since , in addition to the primary GPU, it has a dedicated PhysX GPU on board. If that's not the case, I'd recommend other options.

AS5 takes 200 hours to cure.....as for the HS, how much OC you wanna do ?

For performance and ease of installation, the Prolimatech Megahalems fits both criteria. Here's what I'm putting in new builds Mega w/ IC Diamond TIM and Scythe PWMfans. For moderate OC's, one fan is fine.....you wanna low core temps above 4 GHz, then add the 2nd fan and the cable splitter.

Hard Drives - Check out the performance charts and pick whatever 500 GB per platter drive performs best under your usage patterns. The WD Black 2 TB is a good choice but at smaller capacities, you are limited to the Seagate 7200.12 or the Spinpoint F3. The 7200.12 excels in gaming, multimedia and pictures whereas the F3 wins at music and movie maker. See the comparisons here (copy past link in manually, link won't work in forum):

Can someone explain to me why I should get ASUS P7P55D-E over ASUS SABERTOOTH 55i. The sabertooth appears to be a better motherboard outside of the lack of USB 3.0. I figured that if I get a 3.0 compatible device I could just get a USB 3.0 card...

The p7p55d-e pro is cheaper than that Sabertooth, has SATA III USB 3.0, and the features of the Sabertooth don't look like anything too special. If you feel you could make use if it though, by all means, get it the Sabertooth.
